Explanation for Question 22 From the Math (Calc) Section on the Official Sat Practice Test 8
So question 22 has asked us, which of the following is closest to the 2 percent increase in billions of pounds of plastic produced in the United States 3 from the years, 2000 to 2003. 4 And so the first step is to figure out where are these points on 5 the graph? And so if you do 2000 minus 1985, 6 you get 15. If you do 2003 of 19 minus 1985, 7 you get 18 because there's a difference of three years, 8 right? And we can find those points on the graph here, 9 where we have 15 and where we have 18. 10 Now, if we go up to see the amount of plastic that is produced 11 in those years, we see that we produce a hundred pounds of, 12 or billions of pounds of plastic in 20 or 2000. 13 And we produce 110 billion pounds of plastic in 2003. 14 And the difference between these two is 10, 15 right? Because 110 minus a hundred will give us 10. 16 And now the question is asking us, which is the following is closest to 17 the percent increase, right? So if I went up 10 from 18 a starting point of 100, because 100 was the amount of plastic I had 19 in 2000 that's 0.1 or 10%. 20 So we've experienced a 10% increase in our best answer is going to be 21 a.
